Testing for backdrafting
- Cup your hands around the draft hood (the cone-shaped vertical pipe at the top of your water heater) and see if you feel warm, moist air.
- Place a small mirror by the draft hood, and check back to see if the mirror fogs, which would indicate the presence of moist air.
Can you use PVC for hot water heaters?
The short answer: No. Explanation: PVC is a thermoplastic, and therefore, at some point it will begin to degrade and break down as it’s heated up. It just so happens that Schedule 40 PVC’s maximum operating temperature is 140 degrees Fahrenheit, around the same temperature that hot water gets to in most homes.
